304 EEVISION OF THE GENUS XOTONOMUS. 



iV. violaceomarginatus, and found it identical with the latter. iV. 

 purpureipe7i7iis is founded on the (J. 



NOTONOMUS RUGOSICOLLIS, n.sp. 



(J, Elliptical. Protliorax opaque, densely shagreened and 

 transversely striolate; sides lightly sinuate before basal angles; 

 posterior marginal puncture in lateral channel near basal angle : 

 elytra deeply striate; interstices strongly convex, third narrower 

 than second on basal third, 2-punctate; basal border prominent 

 at humeral angles. Head and prothorax black (a faint purple 

 tinge near sides of prothorax); elytra bronzy-black, submetallic 

 towards sides, metallic behind basal border, ninth interstice and 

 lateral channel of a bright brassy colour; under surface black; 

 legs piceous-black. 



Head not large (2-5 mm. across eyes), subdepressed between 

 eyes, these prominent. Prothorax broader than long (3 x 3 -6 mm), 

 depressed on disc; sides lightly rounded, gently narrowed to apex, 

 very lightly narrowed to base ; anterior angles obtuse ; base 

 (2-7 mm.) wider than apex (2-5 mm.), emarginate in middle; 

 basal angles rectangular; lateral channel wide; median line deep, 

 reaching from base almost to apex; lateral basal impressions long, 

 narrow, deep; posterior part of space between basal impressions 

 longitudinally rugulose but not transversely striolate. Elytra 

 truncate-oval (7*7 x 4*35 mm.), lightly and widely convex, lightly 

 but decidedly convex on each side of apex; sides lightly rounded; 

 basal border arcuate on posterior margin, strongly raised and sub- 

 dentate at humeral angles; lateral channel wide; lateral border 

 narrow, reflexed, not narrower near base; sixth interstice narrowed 

 at base, eighth much wider than ninth on basal half, about as wide 

 as, but much more depressed than, discoidal interstices at middle 

 of length, ninth narrow, convex, interrupted on inner margin by 

 umbilicate punctures, tenth shortly but decidedly developed 

 before lateral apical sinuosity. Intercoxal declivity of prosternum 

 flat; of mesosternum wide, flat. Length 12-5, breadth 4*35 mm.
